Answer:
construction
Step-by-step explanation:
Builders need to know the area and perimeter of a triangle to construct certain buildings.
Answer:
2.6
Step-by-step explanation:
Find one percent by dividing it by 100, then multiply it by 114 and theres your answer.
We are given that:
x is the age, and
y is the heart rate
It is also given that
Now, we have been given that the person’s theoretical maximum heart rate (in heartbeats per minute) is where x is the person’s age in years.
Therefore, 50% of is
Likewise, 75% of is
Which is the same as The system of linear inequalities that describes the given information is y>120-1/2x (for 50% max heart rate) and y<165-3/4x (for 75%).
Thus, y will lie between these two extremes as:
The graph of the same is attached.
Answer:
26 and 27
Step-by-step explanation:
Let the numbers be x and y
x + y = 53
xy = 702
x = 702/y
702/y + y = 53
Multiply through by y
702 + y^2 = 53y
y^2 - 53y + 702 = 0
y^2 - 27y - 26y + 702 = 0
y(y - 27) - 26(y - 27) = 0
(y - 27) (y - 26) = 0
y = 26 or 27
Solve for x in x + y = 53
if y = 26,
x = 53 - 26 = 27
if y = 27,
x = 53 - 27 = 26
The numbers are 26 and 27
